World's Top 10 Youngest Billionaires

Thanks to family inheritances, family businesses, and technology startups, there seem to be more young billionaires today than at any point in history. According to Forbes, the youngest billionaire in the world comes in at just 22 years old, with the tenth youngest being 31 years old. Earlier this year there were reports that Kylie Jenner is on the cusp of being the world's youngest self-made billionaire, a title that Mark Zuckerberg, co-founder and chief executive officer (CEO) of Facebook (FB), earned in 2006 at the age of 23. Jenner has an estimated net worth of $900 million and turned 21 in August 2018.

According to Forbes' 2018 World Billionaires rankings, there were 63 billionaires under the age of 40 with a cumulative wealth of $265 billion. This group is roughly 3% of the total number of world billionaires and about the same in terms of cumulative wealth. Here's how the fortunes of the youngest billionaires have fared over the past few iterations of these rankings.

Let's now take a look the list of this year's youngest rich people in the world:
